|
||||
|
||||
> **开发日期**: 2026-01-02
|
||||
> **开发者**: AI Assistant + 用户
|
||||
> **文档版本**: v1.0
|

> **开发阶段**: Day 2 - REDCap对接与实时同步
|
||||
|
||||
---
|
||||
|
||||
## 📋 开发概述
|
||||
|
||||
Day 2的核心目标是实现 **IIT Manager Agent 与 REDCap 的实时数据集成**，采用 REDCap 原生的 **Data Entry Trigger (DET)** + **REST API** 技术方案，实现零延迟的数据同步和双向通信。
|
||||
|
||||
### 核心价值
|
||||
|
||||
1. ✅ **实时性**: Webhook响应时间<10ms，数据录入后立即触发
|
||||
2. ✅ **可靠性**: DET + 定时轮询双保险机制
|
||||
3. ✅ **云原生**: 完全基于Postgres-Only架构，使用pg-boss队列
|
||||
4. ✅ **标准化**: 符合团队开发规范（队列名称、Worker注册等）
|
||||
|
||||
---
|
||||
|
||||
## 🎯 完成的功能模块
|
||||
|
||||
### 1. RedcapAdapter (API适配器)
|
||||
|
||||
**文件**: `backend/src/modules/iit-manager/adapters/RedcapAdapter.ts`
|
||||
|
||||
**核心功能**:
|
||||
- ✅ `testConnection()` - 连接测试
|
||||
- ✅ `exportMetadata()` - 导出字段定义（17个字段）
|
||||
- ✅ `exportRecords()` - 导出记录（支持全量/增量/指定记录）
|
||||
- ✅ `importRecords()` - 导入记录（Phase 2预留）
|
||||
|
||||
**关键参数**:
|
||||
- `baseUrl`: `http://localhost:8080`
|
||||
- `apiToken`: `FCB30F9CBD12EE9E8E9B3E3A0106701B`
|
||||
- `timeout`: 30秒
|
||||
|
||||
**实际性能**:
|
||||
```
|
||||
- exportMetadata: 260-560ms
|
||||
- exportRecords (全量): 450-1,400ms
|
||||
- exportRecords (增量): 300-800ms
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. WebhookController (Webhook接收器)
|
||||
|
||||
**文件**: `backend/src/modules/iit-manager/controllers/WebhookController.ts`
|
||||
|
||||
**核心逻辑**:
|
||||
```typescript
|
||||
1. 立即返回200 OK（<10ms）
|
||||
2. 验证project_id是否在配置中
|
||||
3. 幂等性检查（防止重复处理）
|
||||
4. 记录审计日志（WEBHOOK_RECEIVED）
|
||||
5. 推送到质控队列（iit_quality_check）
|
||||
```
|
||||
|
||||
**REDCap DET格式支持**:
|
||||
- ✅ 添加了 `application/x-www-form-urlencoded` 解析器
|
||||
- ✅ 支持REDCap原生POST格式
|
||||
|
||||
**Webhook字段**:
|
||||
```json
|
||||
{
|
||||
"project_id": "16",
|
||||
"record": "6",
|
||||
"instrument": "demographics",
|
||||
"redcap_event_name": "",
|
||||
"redcap_version": "15.8.0",
|
||||
"redcap_url": "http://localhost:8080"
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. SyncManager (轮询管理器)
|
||||
|
||||
**文件**: `backend/src/modules/iit-manager/services/SyncManager.ts`
|
||||
|
||||
**核心功能**:
|
||||
- ✅ `initScheduledJob()` - 初始化定时任务（每5分钟）
|
||||
- ✅ `handlePoll()` - 轮询所有active项目
|
||||
- ✅ `manualSync()` - 手动同步指定项目
|
||||
- ✅ `fullSync()` - 全量同步
|
||||
|
||||
**增量同步策略**:
|
||||
```typescript
|
||||
// 基于lastSyncAt时间戳
|
||||
dateRangeBegin: lastSyncAt || createdAt - 24h
|
||||
```
|
||||
|
||||
**审计日志**:
|
||||
- `SCHEDULED_SYNC`: 定时轮询完成
|
||||
- `MANUAL_SYNC`: 手动同步完成
|
||||
- `FULL_SYNC`: 全量同步完成
|
||||
|
||||
---
|
||||
|
||||
### 4. Worker注册 (异步任务处理)
|
||||
|
||||
**文件**: `backend/src/modules/iit-manager/index.ts`
|
||||
|
||||
**注册的Worker**:
|
||||
|
||||
1. **iit_redcap_poll** (定时轮询)
|
||||
- 队列名称: `iit_redcap_poll`
|
||||
- 触发频率: 每5分钟（Cron: `*/5 * * * *`）
|
||||
- 并发数: 1
|
||||
- 功能: 轮询所有active项目的增量数据
|
||||
|
||||
2. **iit_quality_check** (质控任务)
|
||||
- 队列名称: `iit_quality_check`
|
||||
- 触发方式: Webhook/SyncManager推送
|
||||
- 功能: 质控逻辑（Phase 1.5实现）
|
||||
|
||||
**关键修复**:
|
||||
- ❌ 初始: `await jobQueue.work('iit:redcap:poll', ...)`
|
||||
- ✅ 修复: `jobQueue.process('iit_redcap_poll', ...)`
|
||||
- ❌ 初始: 队列名称使用冒号 `iit:quality-check`
|
||||
- ✅ 修复: 使用下划线 `iit_quality_check`
|
||||
|
||||

|
||||
|
||||
### 5. 路由配置
|
||||
|
||||
**文件**: `backend/src/modules/iit-manager/routes/index.ts`
|
||||
|
||||
**注册的API端点**:
|
||||
|
||||
| 端点 | 方法 | 功能 | 状态 |
|
||||
|------|------|------|------|
|
||||
| `/api/v1/iit/health` | GET | 健康检查 | ✅ |
|
||||
| `/api/v1/iit/webhooks/redcap` | POST | DET回调接收 | ✅ |
|
||||
| `/api/v1/iit/webhooks/health` | GET | Webhook健康检查 | ✅ |
|
||||
| `/api/v1/iit/projects/:id/sync` | POST | 手动同步 | ✅ |
|
||||
| `/api/v1/iit/projects/:id/full-sync` | POST | 全量同步 | ✅ |

## 🐛 遇到的问题与解决方案
|
||||
|
||||
### 问题1: 模块路径解析错误
|
||||
|
||||
**错误信息**:
|
||||
```
|
||||
Error [ERR_MODULE_NOT_FOUND]: Cannot find package '@/common'
|
||||
```
|
||||
|
||||
**原因**: 项目使用相对路径，而不是路径别名 `@/common`
|
||||
|
||||
**解决方案**:
|
||||
```typescript
|
||||
// 错误
|
||||
import { logger } from '@/common/logging';
|
||||
import { jobQueue } from '@/common/jobs';
|
||||
|
||||
// 正确
|
||||
import { logger } from '../../../common/logging/index.js';
|
||||
import { jobQueue } from '../../../common/jobs/index.js';
|
||||
```
|
||||
|
||||
**修改文件**: 所有IIT Manager模块的import语句
|
||||
|
||||
---
|
||||
|
||||
### 问题2: 数据库字段名称不一致
|
||||
|
||||
**错误信息**:
|
||||
```sql
|
||||
ERROR: column "redcapProjectId" does not exist
|
||||
```
|
||||
|
||||
**原因**: Prisma使用camelCase，但PostgreSQL实际使用snake_case
|
||||
|
||||
**数据库真实情况**:
|
||||
```sql
|
||||
-- 表名: iit_schema.projects (not IitProject)
|
||||
-- 字段名: redcap_project_id (not redcapProjectId)
|
||||
```
|
||||
|
||||
**解决方案**:
|
||||
1. ✅ TypeScript代码中继续使用Prisma的camelCase（自动映射）
|
||||
2. ✅ 原始SQL语句改为snake_case
|
||||
3. ✅ JSON字段使用 `'{}'::jsonb` 类型转换
|
||||
|
||||
**修改文件**:
|
||||
- 测试脚本中的SQL语句
|
||||
- 文档中的SQL示例
|
||||
|
||||
---
|
||||
|
||||
### 问题3: pg-boss任务名称格式错误
|
||||
|
||||
**错误信息**:
|
||||
```
|
||||
Name can only contain alphanumeric characters, underscores, hyphens, or periods
|
||||
```
|
||||
|
||||
**原因**: 初始使用连字符 `-`，但实际测试发现不稳定
|
||||
|
||||
**团队标准**:
|
||||
```typescript
|
||||
❌ 'iit:quality-check' // 冒号
|
||||
❌ 'iit-quality-check' // 连字符（不稳定）
|
||||
✅ 'iit_quality_check' // 下划线（推荐）
|
||||
```
|
||||
|
||||
**修改**:
|
||||
- `iit:quality-check` → `iit_quality_check`
|
||||
- `iit:redcap:poll` → `iit_redcap_poll`
|
||||
|
||||
**依据文档**: `AIclinicalresearch\docs\02-通用能力层\Postgres-Only异步任务处理指南.md`
|
||||
|
||||
---
|
||||
|
||||
### 问题4: Worker注册方法错误
|
||||
|
||||
**错误**: 使用了 `await jobQueue.work()`
|
||||
|
||||
**正确方法**: 使用 `jobQueue.process()`
|
||||
|
||||
**对比**:
|
||||
```typescript
|
||||
// ❌ 错误
|
||||
await jobQueue.work(
|
||||
'iit_redcap_poll',
|
||||
{ teamSize: 1, teamConcurrency: 1 },
|
||||
async (job) => { ... }
|
||||
);
|
||||
|
||||
// ✅ 正确
|
||||
jobQueue.process('iit_redcap_poll', async (job) => {
|
||||
// ...
|
||||
return { success: true };
|
||||
});
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 问题5: REDCap DET格式不兼容
|
||||
|
||||
**错误信息**:
|
||||
```
|
||||
Unsupported Media Type: application/x-www-form-urlencoded
|
||||
```
|
||||
|
||||
**原因**: REDCap DET发送的是表单格式，而不是JSON
|
||||
|
||||
**解决方案**: 添加Content-Type解析器
|
||||
```typescript
|
||||
fastify.addContentTypeParser(
|
||||
'application/x-www-form-urlencoded',
|
||||
{ parseAs: 'string' },
|
||||
(req, body, done) => {
|
||||
try {
|
||||
const params = new URLSearchParams(body as string);
|
||||
const parsed: any = {};
|
||||
params.forEach((value, key) => {
|
||||
parsed[key] = value;
|
||||
});
|
||||
done(null, parsed);
|
||||
} catch (err: any) {
|
||||
done(err);
|
||||
}
|
||||
}
|
||||
);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 问题6: Docker网络访问问题
|
||||
|
||||
**问题**: REDCap容器无法通过 `localhost` 访问宿主机服务
|
||||
|
||||
**DET URL配置**:
|
||||

||||
```bash
|
||||
docker exec redcap-apache curl http://host.docker.internal:3001/api/v1/iit/health
|
||||
# ✅ 成功返回

## 🎓 经验总结
|
||||
|
||||
### 1. 技术选型验证
|
||||
|
||||
**✅ REDCap DET + REST API方案优势**:
|
||||
- 零开发成本（REDCap原生支持）
|
||||
- 零延迟（实时触发）
|
||||
- 高可靠（Webhook + 轮询双保险）
|
||||
- 易维护（标准HTTP接口）
|
||||
|
||||
**❌ 放弃的方案**:
|
||||
- External Module（需要PHP开发）
|
||||
- 纯轮询（延迟高，资源浪费）
|
||||
|
||||
---
|
||||
|
||||
### 2. 开发规范遵循
|
||||
|
||||
**✅ 符合团队标准**:
|
||||
- 队列名称: 使用下划线（`iit_quality_check`）
|
||||
- Worker注册: 使用 `jobQueue.process()`
|
||||
- 审计日志: 记录所有关键操作
|
||||
- 错误处理: 统一异常捕获和日志记录
|
||||
|
||||
**参考文档**:
|
||||
- `Postgres-Only异步任务处理指南.md`
|
||||
- `REDCap对接技术方案与实施指南.md`
|
||||
|
||||

|
||||
|
||||
### 3. 调试技巧
|
||||
|
||||
**Docker容器调试**:
|
||||
```bash

## 🚀 下一步计划
|
||||
|
||||
### Phase 1.5 - 质控逻辑实现
|
||||
|
||||
**目标**: 实现AI驱动的数据质控
|
||||
|
||||
**核心功能**:
|
||||
1. 实现 `iit_quality_check` Worker的质控逻辑
|
||||
2. 调用Dify工作流进行数据验证
|
||||
3. 生成质控建议（shadow state）
|
||||
4. 返回结果给研究者
|
||||
|
||||
**预估工作量**: 1-2天
|
||||
|
||||
---
|
||||
|
||||
### Phase 2 - 双向同步
|
||||
|
||||
**目标**: 实现AI建议回写到REDCap
|
||||
|
||||
**核心功能**:
|
||||
1. 完善 `importRecords()` API
|
||||
2. 实现shadow state审批流程
|
||||
3. 经研究者确认后同步到REDCap
|
||||
4. 处理冲突和版本控制
|
||||
|
||||
**预估工作量**: 2-3天
